Heated circulator PRO RP 245 EC

Product description
The PRO heating and cooling circulating thermostats are designed for external applications up to 250 °C. Low filling volume permits rapid temperature changes in the connected application. The compact tower design saves installation space. An integrated cooling coil for counter-cooling is fitted as standard. Cooling models enable rapid temperature changes thanks to low filling volume and cooling capacities of 0.6 and 0.8 kW. All units are fitted with a pressure/suction LAUDA Varioflex pump.
